LOCKING WHEELS AND WIRE WHEEL COVERS

VEHICLES AFFECTED: ALL MODELS

The custom locking wire wheel cover package (Option N91/N95) is shipped in the trunk compartment. At the time of delivery of a new vehicle by the carrier, the contents of the package containing option N91/N95 are to be inspected for missing or incorrect parts. Any discrepancies are to be noted on the delivery receipt and a transportation claim is to be filed for any missing or incorrect parts.

The same procedure described above should be followed for all locking wheels and wheel covers.

Replacement of Incorrect or Lost Parts

Canadian Service Parts Operations are currently stocking and servicing some wheel wrenches.

The following types are currently available through GM Parts: Norris Industries, ITT Thompson and Randel Textron (formerly Rockwell).

The types manufactured by McGard Inc. and American Accessories (AMCOR) will continue to be only available through their distributors.

We have put together an attached chart to aid in identifying the various types now in service in order to facilitate the parts required for replacement.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
